from man fdisk:
DESCRIPTION
       fdisk is a dialog-driven program for creation and manipulation of 
partition tables.  It understands GPT, MBR, Sun, SGI and BSD partition tables.

in any case i worked out how to do what i want:
losetup --partscan --find --show sdcard_img

then use /dev/loop0p2 in the original dmsetup command
